11 Claims.

The present invention relates to new and useful improvements in ventilators for windows and has for its primary object to provide a device of this character designed particularly for use in the windows of automobiles and other vehicles.

A further important object of the present invention is to provide a window ventilator of this character adapted for removably positioning in the window frame and embodying a pair of ventilating wings projecting at diametrically opposite sides from the pivotal mounting of the ventilator and adapted for movement into the'desired adjusted position for controlling the admission of air into the window.

Another object is to provide a device of this character of simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture, that may be easily and quickly installed in operative position in the Window frame without necessitating any fastening means therefor and which at the same time is inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure 1 is a View in elevation of the ventilator shown in position in the window frame, the upper and lower portions of the frame being shown in section,

Figure 2 is a transverse sectional view taken substantially on the line 2-2 of'Figure 1,

Figure 3 is a vertical seetional view through the adjustable clamping support for the ventilator,

Figure 4 is a plan View of one of the blanks forming one of the wings of the ventilator,

Figure 5 is a transverse sectional View taken substantially on the line 55 of Figure 3,

Figure 6 is an edge elevational view of the wing frame, and

Figure 7 is a plan view of the cross-head for the top of the clamping support.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention,

the numerals 5 and 6 designate a pair of duplicate wing frames, each of the frames preferably being stamped from sheet metal as shown in Figures 4 and 6 of the drawings, and including a substantially rectangular frame member 1 having each end portion formed with outwardly projecting tabs 8 and one longitudinal edge portion likewise formed with outwardly projecting tabs 9, the tabs being adapted to be bent along the dotted lines shown at H), for folding upon the frame for securing the glass panel H in position in the frame.

The other longitudinal edge of the frame 1 is formed with a longitudinally extending channel I2 having a flange E3 on the outer edge thereof, the channel l2 of the pair of frames being adapted to form a tubular center post M, the flange i3 and the edge of the frame at the side of the channel portion l2 opposite from said flange being provided with openings l5 adapted to receive rivets or the like l6 for securing the frames in flatwise engagement with the respective frames 1 projecting diametrically opposite from the tubular member [4.

Inserted upwardly in the bottom end of the tubular member i4 is a headed stud l1 rising from a plate it, the lower end of the tubular member [4 being bent inwardly as shown at I9 to prevent removal of the head therefrom. The plate It is formed adjacent its outer edge with an upstanding annular rib 29 adapted to reinforce the edge portion of said plate, the rib having spaced openings 2! formed therein. Secured to the under side of the plate is a resilient pad 22, preferably constructed of rubber and adapted to bear against the bottom of the window frame 23. r

The lower edges of the pair of frames or wings I are adapted to enter the openings or notches 2| to secure the wings in rotatably adjusted position in the window frame.

The intermediate portion of the tubular mem ber I i is provided with a pair of inwardly struck lugs 24 forming a support for an expansible coil spring 25 which is positioned in said tubular member, the upper edge ofsaid spring bearing against an adjusting nut 26 threaded on a stem 21 positioned in the tubular member and projecting upwardly from the upper end thereof.

The nut 26 is provided with wings 28 projecting from diametrically opposite sides thereof and slidably positioned in slotted openings 29 formed in the tubular member I 4.

The upper end of the screw 21 is formed with a cross-head 30 on which is suitably secured a rubber pad 3! adapted for bearing against the upper portion of the window frame as shown at 32. The cross-head is formed with an opening 33 adapted to receive the reduced upper end 34 and the screw 27, the end 34 having a loose fit in the opening and upset to permit sufficient tilting of the head in accordance with any inclination occurring frame 32.

Also as shown to advantage in Figure 2 of the drawings, the flanges 13 of each frame member i are engaged by the upper and lower tabs 8 of the adjacent wing frame to assist in securing the pair of frames rigidly together.

From the foregoing it will be apparent that the cross-head at the top of the ventilator serves as an adjustable clamping member for clamping the device in position between the upper and lower edges of the window frame, the nut 26 providing for the proper adjustment of the clamping member and the spring 25 yieldably maintaining the device in position.

It is believed the details of construction, operation and advantages of the device will be readi- 1y understood from the foregoing without further detailed explanation.
